dealer or a
qualified workshop.
Active Lane Keeping
Assist
Refer to the General recommendations on
the use of driving and manoeuvring aids.
Using a
camera located at the top of the
windscreen, the system identifies lane
markings and steers the vehicle inside this lane
to keep it in the lateral position chosen by the
driver.

Conditions for operation
- The adaptive cruise control must be active.
- T he vehicle must be travelling in a traffic
lane clearly delimited by lines on both sides.
-

T
he ESC system must be operating.
-

T
he ASR /DSC systems must not be
deactivated.
-

N
o trailer detected.
-

A s
pare wheel of the "space-saver" type
must not be in use.
-

T
he vehicle must not be subject to strong
lateral accelerations.
-

T
he direction indicators must not be
activated.
Activation/Deactivation
The state of the system stays in the
memory when the ignition is switched off.
The colour of the symbol depends on the
operating state of the system: (grey colour)
At least one of the operating
conditions is not met, the system is
paused.
(green colour)
All operating conditions are met, the
system is active. If the driver no longer wishes to benefit from
the system for a
while, they can deactivate it by
pressing the button again.
The indicator lamp in the button goes off and
the symbol disappears from the instrument
panel.
Cruise control
The driver must hold the steering wheel
properly.
When cruise control is activated, the symbol is
displayed in green: by small steering actions,
the system directs the vehicle and keeps it in
the position chosen by the driver, in the traffic
lane.
The driver can feel movements in the steering
wheel.
This position is not necessarily the centre of
the lane.
The driver can change the position of the
vehicle at any time, by turning the steering
wheel. When the driver feels that the vehicle's
position is appropriate, whilst keeping hands
on the steering wheel, they must release the
pressure to let the system resume control of the
steering, but the vehicle is not centred within
the lane automatically.
This function is primarily suitable for driving on
motor ways and main roads.
F With the adaptive cruise control activated, press this
button.
The action is confirmed by:
-

I
llumination of the indicator lamp in the button in green.
-

D
isplay of the following symbol in the instrument panel.
(orange colour)
The system has a fault.
Driving

153
Pausing/Suspension of the
system
The driver must inter vene as soon as
they believe that the traffic conditions or
the state of the road sur face make this
necessary, by moving the steering wheel
to suspend the system temporarily. Any
action at the brake pedal which results in
the cruise control being paused will also
cause the system to be paused.
If the system detects that the driver is
not holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no reaction
from the driver.
After suspension due to the prolonged
release of the force holding the steering
wheel, you must reactivate the function by
pressing the button again. Automatic pausing:
-

T
riggering of the ESC.
-
P
rolonged failure to detect one of the lane
limit markings. In this case, the active lane
departure warning function can take over,
and the system will reactivate itself once the
operating conditions are again met.
On action by the driver: suspension
-
A

ctivation of the direction indicators.
-
T

ravelling outside the lane limits.
-

T
oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
-

A
ction on the brake pedal (pausing until the
cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal
is pressed).
-

P
ausing the cruise control.
-

D

accompanied by an alert message
and an audible signal.
Active Safety Brake with
Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on
the use of driving and manoeuvring aids
.
This system allows:
-

t
he driver to be warned that their vehicle is
at risk of collision with the vehicle in front,
a pedestrian or, depending on version, a
cyclist,
-

a c
ollision to be prevented, or its severity to
be limited, by reducing the vehicle's speed.
Driving

157
The system also takes motorcyclists and
animals into account; however, animals
below 0.5 m tall and objects on the road
are not necessarily detected.
This system is comprised of three functions:
-

C
ollision Risk Alert,
-
I

ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
The vehicle has a
multifunctional camera
located at the top of the windscreen, and,
depending on version, a radar located in the
front bumper. As soon as the system detects a
potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a
slight noise and a slight
sensation of deceleration.
Deactivation/Activation
By default, the system is automatically
activated at every engine start.
This system can be deactivated or
activated via the Driving /Vehicle
menu of the touch screen.
Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a
message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be
deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required. In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
-

t
owing a trailer,
-
c
arrying long objects on roof bars or roof
rack,
-
w
ith snow chains fitted,
-
b
efore using an automatic car wash, with
the engine running,
-
b
efore placing the vehicle on a rolling road
in a workshop,
-
t
owed vehicle, engine running,
-
d
amaged front bumper (version with radar),
-
f
ollowing an impact to the windscreen close
to the detection camera.
The system is automatically deactivated
after the use of certain "space-saver"
type spare wheels is detected (smaller
diameter).
The system is automatically deactivated
after detection of a fault with the brake
pedal switch or with at least two brake
lamps.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident.

Collision Risk Alert
It warns the driver if their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or
a
pedestrian or cyclist present in your traffic
lane.
The current threshold can be
modified via the Driving /Vehicle
menu of the touch screen.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, several different levels
of alert may be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions and the operation of
the vehicle (cornering, actions on the pedals,
etc.) to trigger the alert at the best moment.
Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The " Vehicle close " message is
displayed.
Level 2 (red) : visual and audible
alert, warning you that a
collision is
imminent.
The message " Brake!" is displayed.
Level 3 : finally, in some cases, a
haptic alert in the form of micro-
braking can be given, confirming the
risk of collision. Where the speed of your vehicle is too
high when approaching another vehicle,
the level 2
alert may be displayed
immediately.
Important: the level 1
alert is never
displayed for a
stationary obstacle or
when the " Close" trigger threshold has
been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid
a collision, this system will supplement the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
After an impact, the function automatically
stops operating. Contact a

CITROËN
dealer or a

qualified workshop to have the
system checked.
